i had a very disturbing noise last weekend from what i thought was a turbo.
it only happened when the car made boost, went away when the car dropped off boost and had me thinking the worst,
The car was still making the same boost pressure just as quickly as it had done before the noise so i didnt wanna beleive that a turbo had gone faulty but it definatly sounded like it.
on inspection i noticed that my ac belt was loose and my alternator belt wasnt the tightest, tightened them both and problem solved,
1 huge sigh of releif later and i was loving my GTR again
bring on some mapping
